Linux Kernel 4.2 已经发布了,这是 Linus Torvalds 近期发布的最大的一个版本,增加了超过100万行代码,移除了大约25万行代码。主要新特性包括:新的AMDGPU驱动;Intel Broxton支持;改进NCQ TRIM处理;F2FS文件系统加密;重写了部分英特尔x86汇编代码;LSM Stacking;延迟梯度网络拥堵控制算法;改进控制组的回写管理等等。
以下内容来自邮件列表:
So judging by how little happened this week, it wouldn’t have been a mistake to release 4.2 last week after all, but hey, there’s certainly a few fixes here, and it’s not like delaying 4.2 for a week should have caused any problems either.
So here it is, and the merge window for 4.3 is now open. I already have a few pending early pull requests, but as usual I’ll start processing them tomorrow and give the release some time to actually sit.
